Hi
We are trying to get the new J2EE connector (the latest source from the
trunk) to work with JBOSS 3.0 RC1. I have successfully deployed the
connector and created a test session bean with container managed
transactions. The bean does the following tasks:
1. gets the Implementation from JNDI
2. calls newDatabase at the implementation object
3. calls makePersistent at the database
4. closes the database.
It seems like there are some problems with the transaction handling. The
transactions are committed twice. The first time the commit is called the
call sequence is as follows:
ojb.odmg.TransactionImpl.commit(TransactionImpl.java:375)
ojb.odmg.J2EETransactionImpl.commit(J2EETransactionImpl.java:107)
ojb.odmg.J2EETransactionImpl.beforeCompletion(J2EETransactionImpl.java:88)
org.jboss.tm.TxCapsule.doBeforeCompletion(TxCapsule.java:1331)
JBoss is calling the beforeCompletion because J2EETransaction implements the
Synchronization interface. Why is this done ? The JBoss should always
retrieve the transaction via the
DatabaseManagedConnection.getLocalTransaction() method.
The second time the transaction is committed an exception is thrown:

JBoss is here calling the commit method at the transaction retrieved via the
DatabaseManagedConnection.getLocalTransaction() method. This is the actual
commit. Any suggestions on how to get this working ??
BTW I am using the following switches in the OJB.properties files regarding
J2EE (I have also tried the default settings):
PersistenceBrokerClass=ojb.broker.ta.PersistenceBrokerJ2EEImpl
PersistenceBrokerFactoryClass=ojb.broker.ta.PersistenceBrokerFactoryJ2EEImpl
